Autogas, also LPG (liquified petroleum gas) is a liquid gas that can be used in cars as a fuel.

General

Due to the current discussions about global warming, CO2 emissions and rising fuel prices, fossil fuels are becoming more and more popular. The autogas system is most commonly installed in passenger cars, here in germany.

History

autogas became "famous" in italy already in the 70s. It was immediately accepted there and even today a lot of vehicles there run on LPG. In istanbul, autogas has also become established, and all cabs there run on liquefied petroleum gas. In the 80’s it was also known in austria, but quickly forgotten, because autogas was highly taxed there. Today, however, all regular-service buses in Austria run on the propane/butane mixture.

Vehicle conversion

The conversion to LPG is possible in any car with a gasoline engine, regardless of power and number of cylinders. Older vehicles (before year 98) are usually equipped with a semi-automatic system that uses a common injection system, as the engine control units do not support any other type of control. Prices vary between 1400 and 3500€.

Special autogas tanks, mostly steel tanks, are used as fuel tanks for autogas vehicles. The tanks can be installed inside the vehicle, z.B. In the spare wheel well in the trunk, or mounted as underfloor tanks. Autogas is used under relatively low pressures of approx. 8 bar stored in liquid form in the autogas tank (for comparison: natural gas approx. 200 bar). This means that even relatively small autogas tanks can cover long distances. Depending on the type of vehicle and the way it is driven, 400 to 600 kilometers can be easily covered on a single tank of gas.

Cylinder tank in the trunk

Refueling is exactly the same as with a normal tank. The nozzle is mounted next to the petrol nozzle.

Function

From the basic structure, an evaporator pressure regulator converts the autogas, which comes from the tank in liquid form, into a gaseous state. At the same time, the gas is reduced to the pressure required for combustion. Modern autogas systems are similar to gasoline injection systems and record a large number of engine parameters to control the mixture formation. the system feeds the gas with overpressure in separate lines directly to the intake valves of the individual cylinders. A microprocessor regulates the autogas drive and thus ensures low-pollutant and efficiency-optimized combustion in the engine.

The special properties of liquefied petroleum gas allow both gaseous and liquid autogas to be injected. In contrast to gas injection systems, liquid injection systems do not have an evaporator. In these systems, a pump installed in the autogas tank with a pressure regulator ensures a constant pressure in front of the injectors.

Technology

The vehicle can run on gas only (monovalent) or automatically or manually switch between gas and petrol (bivalent). the bivalent drive offers such a plus point, namely a significantly higher range of up to 1000km.

6 min evolutions and visions in the automotive world – from yesterday, today and tomorrow.

Faster, better, more efficient – a lot has happened in the automotive world since carl benz introduced the first internal combustion engine tricycle in 1886. Almost everyone in the world has a comfortable four-wheeled vehicle nowadays. But the story is still far from being finished. Take a look at recent developments in the automotive industry and current visions. What could the car of the future look like??

Milestones of the automotive industry in 20. – 21. Century

1990 the japanese automotive industry experienced a veritable boom. Through the invention of the airbag cars became a lot safer and the newly introduced three-way catalytic converters reduced emissions significantly. But not only that. The engine has also been given a groundbreaking update: the invention of electronic fuel injection enabled better performance with lower consumption.

The year 2000 was the birth year of the hybrid technology, reducing fuel consumption and protecting the environment. Today’s hybrid cars have an internal combustion engine and an electric motor. The latter is powered by batteries that are charged by kinetic energy. Thanks to the low emissions of the engine, the pollution index of the hybrid car is significantly lower.

In the 2000s, the introduction of autonomous parking the first step toward autonomous driving is taken. A foretaste of the future of the car?

From approx. 2010 the electric car thanks to the development of cheaper and more efficient batteries more and more marketable. The all-electric engine is equipped with a solid-state battery, which makes a range of over 300 km possible. the electric car does not emit any pollutants while driving. Using renewable energy to charge the engine significantly reduces emissions.

Since the 2010s, more and more vehicles have been built internationally charging stations built to prevent "range anxiety". Because the biggest weakness of electric cars is still their comparatively short range. You can’t get as far on a charged battery as you can on a full tank of gas. In addition, it still takes a long time to charge the battery. However, work is already underway on technologies for fast charging being worked on.

The car of the future – here’s how it could work

According to forecasts by experts 2020 the hydrogen car increasingly safe and thus more marketable. mercedes-benz presented the first fuel cell car back in 1994. At that time, the individual parts of the engine and the production of the hydrogen were still too expensive, so that the market launch was not yet possible.Ca. 2020 it should be possible, hydrogen from renewable energy sources which could make the hydrogen car even more environmentally friendly than it already is: the electric motor in these cars is powered by combining hydrogen with oxygen. Water is a by-product and no emissions are produced. Thus, driving a hydrogen car is largely CO²-neutral.

The range could be almost as long as that of cars with internal combustion engines – and that with a refueling time of just three to five minutes. With one kilogram of hydrogen, they would then be able to drive around. 100 km driving.

Disadvantages: hydrogen is extremely flammable. Engineers and scientists have yet to find a solution to this problem. In addition, new filling stations would have to be set up throughout Germany and internationally if the hydrogen car were to become established.

The self-driving cars are coming

From 2030 could self-driving cars also take on complex tasks, which would make the steering wheel superfluous. The driver could read a book while driving and arrive relaxed at his destination, while the computer-controlled car would do the driving for him.

In addition, the self-driving car could. recharge themselves and be equipped with automated facial recognition, so it could pick up people without a driver. Thanks to automatic communication with other vehicles, the future could be preventing traffic jams and rear-end collisions become. Connecting to the internet would make a self-driving car fast finding alternative routes. Thus it would not only be safer, but also more efficient than a car controlled by humans.

disadvantages of self-driving cars:

In the event of a poor or no internet connection the vehicle would no longer be usable under certain circumstances.
In addition every possible traffic situation to be programmed for the computer, so that he can react to it. Here the possibilities are almost infinite.
Technical errors could have devastating consequences.

by the way, an underground tunnel is already being tested in hawthorne, california, where autonomous electric cars could travel at speeds of up to 240 kph. this should prevent traffic chaos in cities and on highways.

Flying cars and cars on legs?

Already, flying "car-like" vehicles are being tested in several countries, such as the united arab emirates. These first pioneers are designed as cabs and are not initially intended for private use.

Ca. 2040 could flying cars be equipped with an all-electric battery-powered engine, which would reduce their emissions. In addition, the already established autonomous driving could facilitate the operation of these vehicles and increase traffic safety.

So the acquisition of a flying car will be a long time coming – and it would also be very expensive. The new way of getting around would also require a new kind of driver’s license. In bad weather conditions, flying could also be associated with higher risks than conventional driving on the road.

A possible alternative cars on legs dar. At this year’s consumer electronics show (CES) in las vegas, the first plans were already on display. These insect-like cars could look like they’re straight out of a hollywood movie.

Whether it’s a car of the future or a classic car, you’ll always find the right car insurance for your vehicle at verti. Calculate your low fare with us now.

Marco reus on the road for years without a valid driver’s license | can he ever do car commercials again?

Yesterday at BVB training: reus strokes his hair, looking thoughtful photo: AP/dpa

BILD revealed: marco reus (25) must pay 540,000 euro fine for driving without a license. Now it turns out: the national player had a dutch driver’s license – a fake one!

BILD comment

Matthias brugelmann from the BILD editorial department comments on the case of marco reus, who drove for years with a forged driver’s license.

Marco reus and the driver’s license scandal: the case is a feast for the internet. BILD shows the funniest contributions.

The case marco reus. Now it comes out: apparently he had a fake driver’s license! This is reported by WDR.

WDR quotes from the warrant: "in 2009, you obtained a dutch driver’s license through an unknown contact person, knowing that it did not entitle you to drive motor vehicles in germany. This one is a forgery."

Who gave reus his fake driver’s license?? Since 1. July 2009 he played in gladbach (20 kilometers from holland).

As a justice spokesman confirmed to BILD, reus was also investigated for document forgery. He had on 18. March presented the invalid driver’s license. The investigation was discontinued because he was already facing a higher penalty for driving without a license. The reus side did not want to comment to BILD.

Is the league experiencing a new driving license scandal??

in may 2008 it was revealed that a driving instructor from lower saxony, driving examiners and accomplices had "helped" about 50 professionals.

Also interesting

may reus continue to advertise cars?

The midfield star was part of a campaign of BVB sponsor opel. Whether this will be continued is open.

Opel explained: "of course, the case has surprised us. We know that our partner BVB dortmund has discussed and clarified the issue with marco reus. We have nothing to add."

Not the only car ad with reus!

Before the world cup in brazil, photos of the BVB star were taken – sitting on a mercedes (DFB sponsor).

In addition, reus advertises for the mineral oil company aral. On his facebook page, he wrote in june: "just fill up, collect points and dust off bonuses."

Almost curious: at toy manufacturer mattel, reus advertises the "hot wheels" model cars.

How dortmund reacts?

Reus had a serious one-on-one talk with trainer jurgen klopp (47). Klopp: "at some point in his life, to stay on topic, he made a wrong turn as a very young guy."

And: "he’s maximally insightful. A stupid story where there is no real way out until you get caught. For this he gets an extraordinarily high penalty, which is then also in order."

How does dortmund evaluate that reus was on the road with forged papers according to the criminal warrant?

BVB boss hans-joachim watzke (55): "this incident has also obviously been assessed under criminal law. That’s all I can say on the subject."

Nevertheless, watzke puts himself in front of his employee: "what marco did was serious. He has received a severe and just punishment for it. I know from conversations with him that he deeply regrets the matter. All BVB officials stand united with marco."
